It is generally not recommended to drink alcohol while taking allergy medications, especially certain types.
First-Generation Allergy Medications
First-generation allergy meds like diphenhydramine (Benadryl), chlorpheniramine, clemastine, and hydroxyzine should never be combined with alcohol. Both these medications and alcohol cause drowsiness and central nervous system depression, which can dangerously amplify sedative effects and impair functioning.
Second-Generation Allergy Medications
Second-generation allergy medications such as loratadine (Claritin) and cetirizine (Zyrtec) tend to cause less drowsiness than the first-generation ones. Drinking moderate amounts of alcohol while on these medications might be tolerated by some people, but it can still increase side effects like drowsiness, dizziness, and impairment. Caution is advised, especially avoiding driving or operating machinery while combining the two.
Summary
- Avoid alcohol entirely with first-generation antihistamines like Benadryl due to severe sedation risks.
- Moderate alcohol intake may be possible with second-generation antihistamines like Claritin or Zyrtec, but it can increase drowsiness and other side effects.
- Always consider personal tolerance and medical advice; if uncertain, it is safest to avoid alcohol while on allergy medication.
Therefore, drinking on allergy meds depends on the type of medication, but the safest practice is to avoid alcohol to prevent enhanced side effects and health risks.
